Using the blinq device to detect common vision problems

Amblyopia is a common vision problem in children, affecting 2 to 3 in 100, and can be caught early and can often be corrected. A study examined the accuracy of Rebion’s blinq pediatric vision scanner for accuracy in diagnosing amblyopia and strabismus.1

The researchers conducted a cross-sectional diagnostic accuracy study. Participants ages 1 to 20 were enrolled and tested by people who masked the diagnosis. They were then given a complete ophthalmic examination by a pediatric ophthalmologist who was masked from the screening result. Separate analyzes were used for participants previously treated for amblyopia or strabismus.

A total of 193 participants were included in the analysis, with 53 previously treated and 140 previously untreated. Of the previously untreated participants, 65 had amblyopia or strabismus; 11 had risk factors/suspected binocular vision deficiency without amblyopia or strabismus; and the other 64 were control. Researchers found that the sensitivity was 100%, as all 66 patients with an eye condition that warranted a referral received one. The 5 patients who had intermittent strabismus and passed were considered an “acceptable pass” due to patient risk factors and amblyogenic potential. Seven erroneous references meant 91% specificity. After analyzing a subcohort of children aged 2 to 8 years, researchers found similar results (sensitivity 100%; specificity 89%).

The researchers concluded that the device had high sensitivity and specificity when it came to detecting referral-justified unilateral amblyopia and strabismus. Using the device with visual screening programs could potentially improve disease detection and reduce false referrals. In a press release announcing the study results, Justin Shaka, CEO of Rebion said, “The blinq vision scanner is a powerful tool in the fight to eliminate vision loss due to amblyopia and strabismus. By putting our technology in the hands of every pediatric practice and Every preschool vision screening program in the country, blinq empowers primary care screeners to prioritize those most in need of specialist care.”2
